But Katie has warned the wannabes hoping to find fame and fortune through her show they cannot be famous for nothing.

Katie said: "A lot of people that came through, you could see that they just want the fame, they're not really interested in anything else, 'cause I could tell by the questions I was asking them.

"So they wouldn't have a chance anyway. I would listen to what people are saying. They have to say the right thing.

"Anyone can come along to an audition and say 'I wanna be famous, I wanna do this and that' but then you say 'OK, but famous for what?'

"You'll see in the show they've got to be smart, shrewd, hungry and really want it."

She added: "Looks helps. You can't be pig ugly, let's be honest. You're not going to buy a pig ugly person on a calendar are you? Well I wouldn't.

"They've got to have looks, they've got to have an aura about them, a bit of star quality."

The show will see Katie and a panel of judges whittle down hundreds of wannabes to one winner through auditions and a set of challenges to see if they can handle the same tasks Katie does as part of her career.

The model said: "There's always room for different reality shows and mine's different to any of the others. I think all the shows out there, some of them might have the same kind of concept, but what they're about they are all different."
